You buy it. I don't know exactly how it's made, but I'm pretty sure that it's not the kind of thing that you can make very easily without professional (and very specialized) equipment. Trying to make these highly energetic compounds yourself is silly, dangerous, and unnecessary. On the other hand.. You can buy it from Amazon for pretty cheap.
On that note, if you're going to be using it, be extremely careful. Unless you really know what you're doing, stay away from the stuff. 18M sulfuric acid will burn holes through paper, your clothes, etc. etc. within seconds. When mixed with water, it can cause the water to come to a boil instantly. If you try to dilute it with water (which you should never do with strong acids; you always had acid to water, and not the other way around) then the pure sulfuric acid will bubble everywhere.
The good thing about it is that if it gets on your skin, you will certainly feel it, and if you wash it off fast enough, it won't cause too much damage. Nonetheless, if you get a ton of it on you, you are in real trouble. If it gets in your eyes, then you're really screwed.
Sulfuric acid is a stronger base, meaning it more completely dissociates. Acetic acid does not completely dissociate, and therefore does not change the concentration of hydrogen ions in solution to the extent that sulfuric acid does. Since pH = -log[Hydrogen ions], sulfuric acid will have a lower pH.
take 276 gm of salicylic acid in 1000 ml water to prepare 2M solution of the salicylic acid.
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.
No, a sulfuric acid solution in water is homogeneous

H+, OH-, SO42- ions
Not necessarily or even usually. The term "one molar" refers to the concentration of the acid added and does not have anything to do with the concentration of ferrous ions.

Mix 90ml. sulfuric acid with 10ml. water, to this add 0.5gm. diphenylamine
The molar mass of sulfuric acid is 98 grams per mole.
These are two different compounds.
This means that one liter of the solution of sulfuric acid contains 0.2 gram-equivalent mass of sulfuric acid. For this acid, the equivalent mass is one half the molar mass, since each molecule of H2SO4 supplies two hydrogen atoms to neutralize alkaline materials.
If you have a standard solution of an acid, like hydrochloric or sulfuric, you can perform a titration in the presence of phenolphtalein or methyl orange and calculate the solution's normality or, you can weigh a sample of a strong solid acid ( orthoiperiodic acid or even oxalic acid), titrate the acid with the hydroxide solution, again in the presence of phenolphtalein or methyl orange and calculate the concentration of NaOH. If you want to have a solution with an exact concentration, let's say 1 molar, and the actual concentration is 1,33 molar, you simply calculate how much water you need to ad in a specific quantity of solution, to dilute it to exactly 1 molar.
